LUBRICATOR.

Specification of Letters Patent. l

Patented Dee. 31, 1912.

T 0 all whom t may concern:

Be it known that we, FRANK P. DAY and CHARLES C. HAnTzocE, citizens ofthe United States of America, residing at Monroe, in the parish ofOuachita and State of Louisiaaa, have invented new and usefulImprovements in Lubricators, of which the following is a speclcation.

Our presentinvention relates to improvements in lubricators orlubricating devices and has particular application to feedingattachments for engine lubricators.

In carrying out this invention, it' is our purpose to provide anattachment of this character whereby the lubricant or lubricating oilmay be fed from a reservoir or container to a battery of engines orthelike in order to properly lubricate the' same, Water of condensationserving to float the oil in the reservoir or container and supply thesame to the lubricator, preferably sight feed, thence to the cylindersofthe engines or the like apparatus.

Furthermore, we aim to provide a lubricating device of this type whereinthe lubricant may be fed to the engine cylinders irrespective of thelling of the reservoir. In other words, the invention involves a by-passaround the reservoir whereby the water of condensation may act upon thelubricant to supply the same to t-he engine cylinders when the reservoirsupply has been cut off for filling purposes.

lVith the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the appended claims.

In the accompanying drawing, the figure is a diagrammatic View showingcert-ain of the parts in section.' Y

Referring to the accompanying drawing in detail, a steam main isdesignated at 1 and as shown has communication with an engine cylinder 2by way of a pipe 3 equipped with a controlling valve 4 so thatcommunication between the steam main and the engine cylinder may be cutofwlien desired. Conveniently located with respect to the enginecylinder, is a lubricant reservoir or container 5 provided with theusual gage or sight glass G and equipped with a dome 7 in communicationwith the reservoir and closed by means of a filling plug or cap 8.Connected to the steam main l and in open communication therewith at anappropriate distance from the pipe 8, is a condenser 9 havingcommunication with the reservoir 5 by way of a pipe 10 equipped with avcontrolling lValve `11 and designed\to supply the water of condensationto the reservoir 5 so that the oil or other lubricant within suchreservoir may be floated therein and driven into the dome 7. Arrangedwithin the reservoir 5 and extending into the dome 7 is a lubricantconveying pipe 12 the eX- posed or free end of which is connected to anauxiliary multiple sight feed reservoir 13 so tha-t in the oating of theoil within the reservoir, the former may be conveyed to the lubricator13, thence to the cylinders of the engine in a manner to be presentlydescribed. A valve 14 is located within the pipe 12 so thatcommunication may be established between and cut ofi from the containerand lubricator when desired or necessary. The auxiliary reservoir 13 asshown is in open communication with a distributing main 15 provided witha plurality of sight feed lubricators 16, one of which is connected tothe pipe 3 of the engine cylinder 2 while the others are adapted forcommunication with other engines or the like apparatus so that aplurality of engines may be lubricated or oiled from a common source ofsupply, thereby preventing waste of the lubricant and reducing the costof lubricationl to'a minimum.

When the lubricant wit-hin the reservoir has been exhausted, and it isdesired to refill the reservoir or container, the valves 11 and 14 areclosed, and the Water of condensation within the reservoir drained byway of a drain cock 17, subsequent to which action the filling plug isremoved to facilit-ate the refilling of the reservoir.

Heretofore, in the construction of lubricators of this type, thelubricant supplied to the engine cyllnders has been cut ofi" in thefilling of the reservoir, whereby the engines have been obliged tooperate without oil for a certain period of time. In order to overcomethis object-ion and supply oil to the cylinders of the engine or otherapparatus during the filling of the oil container or reservolr, we haveprovided a by-pass around the containerand in communication with thecondenser and auxiliary reservoir so that when the container has beencut out of service, the residual lubricant within the auxiliaryreservoir may be forced into the engine cylinders,

said residual lubricant being usually sutlcient to keep the cylindersoiled during the refilling or recharging of 'the reservoir.' Thisby-pass as shown, includes a pipe 18 connected atone end to the pipe 10immediately adjacent the juncture of the lat* ter pipe with thecondenser 9, and having its opposite end depending into the auxiliarylreservoir 13, a suitable valve 19 being interposed between the ends ofthe pipe 18 so that the by-pass may be cut out in the normal operationof the oiler or lubricator.

From the above description taken in connection with the accompanyingdrawing, it will be seen that we have provided a lubricator for engineswhich may be operated at all times irrespective of the condition of the,oil within the reservoir and whereby a plurality of engines or the likemay be supplied with a lubricant from a single source ofsupply.

We claim:

1. In a lubricator, a steam main, a condenser in communication with saidmain, a lubricant container in communication with said condenser, anauxiliary reservoir in communication with said container and adapted tosupply oil to an engine cylinder; and a by-pass around said containerand designed to establish communication between said condenser andauxiliary reser- Voir whereby said auxiliary reservoir may be operatedindependently ot the container.

2. In a device oi the class described,fa

Loaaoaa steam main, a condenser in communication with said main, acontainer in communica tion with the condenser, an auxiliary reservoirin communication with the container,v a

distributing main in communication with the auxiliary reservoir andadapted to supply a lubricant to a plurality of engine cylinders; and aby-pass around said container and between'said condenser and auxiliaryreservoir whereby said auxiliary reservoir may be operated independentlyof the container.

3. In a lubricator, a steam main, a condenser in communication with saidmain, a lubricant container in communication with said condenser, anauxiliary reservoir, a conduit connecting said auxiliary reservoir withsaid container, a by-pass around said container and designed toestablish communication between said condenser and auxiliary reservoirwhereby the auxiliary reser- Voir may be operated independently of thecontainer, and means in said conduit and by-pass and o erableindependently of each other to cut o communication between saidcontainer and auxiliary reservoir and the condenser and auxiliaryreservoir.

In testimony whereof we atix our signatures in presence of twowitnesses.
